Shareholders are the beneficiaries.
I guess since you are posting from Spain, you'd hardly notice the 23% real unemployment here in the USA. But from what I hear, the economies of Spain, Portugal, Ireland, Greece, Italy, etc., are suffering from the same Free Traitor, myopic, tunnel vision, stupidity as ours is.
Shareholders also benefitted when nations had sustainable, fully functioning economies. Those economies also had a balance of production, consumption, distribution, exports, and imports, such that that vast majorities of those economies were gainfully employed within their economies.
Globalism is simply communist redistribution of wealth to the few privileged, and redistribution of poverty to the masses.
Otherwise, our economy and those of all the above mentioned nations would be booming. That is not the case.
The concept of outsourcing by US based multinationals as a form of communism is a truly head-spinning example of "words mean exactly what I say they do".
